I have seen a hell of a lot of systems coming go over the years but I have never heard of any system professional institutional or individual that has ever been able to maintain that kind of a win ratio
Of all the stats related to trading, win percentage is one of the least significant. I can design a system that has 90% winners but it will lose a fortune. High win percentage systems typically violate the first rule of trading, let your profits run and cut your losses short.
Even though I understand all that, I must say I find a high win percentage to be gratifying. Very gratifying. But it is ego gratification. That's why trading is so tough. It seduces you into things that are suboptimal but which feel good at the time.
